Syntax

Charge Density [{of} SpeciesName] = Polynomial [Variable = variable | Order = order | Variable_Offset = variable_offset | C0 = c0 | C1 = c1 | C2 = c2 | C3 = c3 | C4 = c4 | C5 = c5 | C6 = c6 | C7 = c7 | C8 = c8]

Scope

Aria Material

Summary

Value from a polynomial function

Description

The value, \phi, is calculated as \phi = \sum_i^n C_i (X + X_0)^i where X_0 is the variable offset, X is the variable, n is the order and the coefficients provided are C_i
